HarmonyOS 请问ArkTS如何创建全局文件？

export class GlobalTest { 
  static readonly Debug: string = 'www.productxxx.com'; 
  static readonly Realse: string = 'www.testxxx.com'; 
  //文字color 
  static readonly WHITE: Color = Color.White; 
  static readonly BLUE: Color = Color.Blue; 
  static readonly BLACK: Color = Color.Black; 
  //文字size 
  static readonly SIZE_SMALL: number = 4; 
  static readonly SIZE_BIG: number = 8; 
}

{ 
  "float": [ 
  { 
    "name": "splash_image_size", 
  "value": "120vp" 
  }, 
  { 
    "name": "splash_image_size_lg", 
  "value": "160vp" 
  }, 
  { 
    "name": "splash_text_margin_bottom", 
  "value": "136vp" 
  }, 
  { 
    "name": "text_image_width", 
  "value": "114vp" 
  }, 
  { 
    "name": "bar_width", 
  "value": "96vp" 
  } 
  ] 
} 
//在引用界面 
Text('测试') 
  .fontSize($r('app.float.micro_font_size')) 
//这样去使用float.json文件 
//同理创建网络方面的json文件 
{ 
  "string": [ 
  { 
    "name": "debug", 
  "value": "www.productxxx.com" 
  }, 
  { 
    "name": "Realse", 
  "value": "www.testxxx.com" 
  } 
  ] 
}
